Hi Jeremiah, There's currently no way to do that. I think the best way to modify the existing ElasticsearchSystemProducer would be to add a config option for a callback to let you customize this behavior. Basically, a pluggable listener ( https://github.com/apache/samza/blob/master/samza-elasticsearch/src/main/java/org/apache/samza/system/elasticsearch/ElasticsearchSystemProducer.java#L101 ).
